Re: abusive sensei
first of all on my choosing the word abusive, to me the situation i saw fitted that a perosn of authority purposely inflicting pain to those beneath him, with the underlying promise that if they take the pain then he'll teach them more. this is just me idea not a dictionary defininition and i apologise if anyone is sensetive to that particular word
Adam the training you descride doesn't sound rough, and you made a couple of references to the lack of pain you feel during techniques, that is my point. hard trianing is ok but not intentional hurting people when you have them at your mercy there is no real learning or teaching going on at that point.
to refer to these people as tough or strict teachers i also feel is incorrect. being tough or strict implies that you have a set of rules and stict rigidly to them, or you have high exacting standard of your students. how does locking people till they scream acomplish this? and in the story i stated above, a smaller you beginner girl what mistke could she have purposely done to bring out this strctness.
i have had another teacher who once you got to a certain level would throw you progressively harder as you went up the grades to continuely test your ukemi and i think that is more correct. however this teacher took no pleasure in locking people up hard.
